mdns-scan is a tool for scanning for mDNS/DNS-SD published services on the
local network. It issues a mDNS PTR query to the special RR
_services._dns-sd._udp.local for retrieving a list of all currently registered
services on the local link.
mdns-scan is not a good mDNS citizen since it queries continuously for services
and doesn't implement features like Duplicate Suppression. It is intended for
usage as a debugging tool only.
mdns-scan is incomplete since it doesn't resolve mDNS services for you - it
just dumps their PTR RRs. To understand these records you need minimal
knowledge of DNS-SD and how it works.
mdns-scan does not terminate on its own behalf. It scans for services
continuously until the user kills it by pressing C-c.
mdns-scan does not rely on a local mDNS responder daemon. It has no
dependencies besides the GNU libc. It has been tested on Linux only.
mdns-scan does NOT scan for local mDNS enabled hosts or A/AAAA RRs, it scans
for DNS-SD registered services, nothing else.

default one.
